After watching the thing I'm not so sure the drop isn't part of the problem. It may drop before the fletch gets there, but not out of the way. It's inability to get out of the way is a problem some rests have and a higher/stiffer vane like a blazer would just make matters worse. This nock would have to be set quit a bit higher for contact to be avoided. Not saying it's totaly to blame, that arrow is suspect. If I was a betting man I'd say it was a GT XT. I and many others have had those explode before. Mine did itright where that shaft bent.

The same test with different arrows would be interesting. Still based on that video I would/will avoid rest with large launchers.

If you take controll of the video feed and just look at snap shots the launcher even without the shaft bending would still be in the way of the fletch. It's the same as trying to shoot a prong rest with the cock vane up. Look how high it sits on the shelf. It's fast enough to croos the street in traffic, but unfortunetly it stops in front of it.
